Acoustic Research AR PS2062 Main / Stereo Speaker

Pros: Great quality at a low price and sound better than many expensive brands.
Cons: Try to find a pair.

These speakers sound very good and they could be bought for under $100 at one point. I have a full 5.1 surround set up with these speakers and they sound better than most. These are large bookshelf speakers and the quality of the materials is very good.
